The complex `Hg[Co(CNS)_(4)]` is correctly named as

The complex Hg[Co(CNS)_(4)] is named as :

The name of complex [Fe(CN)_6]^(3-) is

The freezing point of an aqueous solution of KCN containing 0.1892 mol kg^(-1) was -0.704^(circ)C . On adding 0.45 mole of Hg(CN)_(2) , the freezing point of the solution was =0.620^(circ)C . If whole of Hg(CN)_(2) is used in complex formation according to the equation, Hg(CN)_(2)+mKCN rarrK_(m)[Hg(CN)_(m+2)] what is the formula of the complex ? Assume [Hg(CN)_(m+2)]^(m-) is not ionised and the complex molecule is 100% ionised. (K_(f)(H_(2)O) is 1.86 kg mol^(-1) K .)
